A preliminary analysis has been performed to understand the effect of surface roughness height on the evolution of the density currents generated in lock-exchange mechanism. The results have revealed density currents over rough wall travel at a lower speed compared to those over smooth wall. Further, a regression analysis has revealed that the maximum front velocity varies as ek, where k is the height of the surface roughness.
